Description
Technical Field
The utility model relates to a weft thread device for fishing net machine.
Background
The fishing net machine is a machine for fishing and producing fishing nets, more widely speaking, the fishing net machine is a mechanized tool for producing various nets such as fishing nets, bird prevention nets, sports nets and the like, and compared with the traditional manual net weaving mode, the labor productivity and the product quality are greatly improved. And when the fishing net is woven to the fishing net machine, make through warp and weft cooperation, among the prior art, weft passes through the cam and drives for driven swing arm pulling shuttle case, and then pull out weft. However, in this way, the resistance of the weft thread to be delivered when the thread spool is shallow is greater than that when the thread spool is full, which leads to the same swing amplitude and less weft thread delivery, thus causing the problem of large and small meshes after the fishing net is knitted.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a structure is adjusted in weft compensation can be according to the settlement parameter, adjusts the amplitude of oscillation of driven swing arm, and then makes the shuttle case reciprocating displacement increase, and the weft of seeing off increases, and then can compensate weft and send the volume, avoids big or small net purpose problem.
In order to realize the above-mentioned purpose, the utility model provides a structure is adjusted in weft compensation, which comprises a frame, be provided with the shuttle case in the frame, be provided with the shuttle in the shuttle case, be provided with the drum on the shuttle, shuttle case both ends link to each other with the trailing arm, be provided with the weft axle on the trailing arm, the weft axle links to each other with adjustment mechanism, the supporting weft swing arm that is provided with of adjustment mechanism, the weft swing arm links to each other with the connecting rod, the connecting rod links to each other with big swing arm, big swing arm sets up with the cam cooperation, the cam cover is established on the driving shaft.
Compared with the prior art, the utility model has the advantages that the driving shaft rotates to drive the cam to rotate, and then the cam is contacted with the large swing arm, so that the large swing arm swings and further drives the connecting rod to move, so that the connecting rod drives the weft swing arm to move towards the adjusting mechanism, because the adjusting mechanism is fixed on the weft shaft, the adjusting mechanism is pushed by the weft swing arm and further rotates a certain angle, thereby driving the weft shaft to rotate, because the driven swing arm is fixed on the weft shaft and further rotates a certain angle outwards, the shuttle box is pulled by the driven swing arm to move outwards, thereby realizing the delivery of the weft, because the adjusting mechanism can adjust the distance between the adjusting mechanism and the weft swing arm, further the adjusting mechanism can be contacted with the weft swing arm earlier, further the rotating angle of the weft shaft is increased, when the weft is wound, the increase of weft volume of sending out compares the volume of sending out when full drum and is equivalent, avoids the problem of big or small mesh, the utility model discloses can be used to the fishing net machine.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
the weft compensation adjusting structure shown in fig. 1-3 comprises a frame 1, wherein a shuttle box 4 is arranged on the frame 1, a shuttle 3 is arranged in the shuttle box 4, a wire coil 2 is arranged on the shuttle 3, two ends of the shuttle box 4 are connected with driven arms 13, weft shafts 10 are arranged on the driven arms 13, the weft shafts 10 are connected with an adjusting mechanism, a weft swing arm 8 is arranged on the adjusting mechanism in a matching way, the weft swing arm 8 is connected with a connecting rod 7, the connecting rod 7 is connected with a large swing arm 6, the large swing arm 6 is arranged in a matching way with a cam 11, and the cam 11 is sleeved on a driving shaft 5; the adjusting mechanism comprises a base arranged on the weft swing arm 8, a servo motor 12 is arranged on the base, the base is arranged on a weft shaft 10, the shaft end of the servo motor 12 is connected with a connecting sleeve 19, a screw rod 17 is inserted into the connecting sleeve 19, an internal thread matched with the screw rod 17 is arranged in the connecting sleeve 19, and the screw rod 17 is arranged right opposite to the upper part of the weft swing arm 8; the machine base comprises a mounting plate 18, a mounting frame 16 is arranged on the mounting plate 18, the servo motor 12 is arranged on the mounting frame 16, one end of a connecting sleeve 19 is connected with the servo motor 12, the other end of the connecting sleeve passes through the mounting plate 18 and is inserted into a lead screw 17, a pair of fixed arms 15 are arranged on two sides of the mounting plate 18, a shaft sleeve 14 is arranged at the end of each fixed arm 15, and one end of a weft shaft 10 passes through the shaft sleeve 14 and is fixedly connected with the shaft sleeve 14; the fixing arm 15 is arranged obliquely downwards; the weft swing arm 8 is sleeved with a bearing 9 with a seat, and the bearing 9 with the seat is arranged between the driven swing arm and the base and is fixedly connected with the frame 1.
The utility model discloses in, driving shaft 5 rotates and drives cam 11 and rotates, and then cam 11 and the contact of big swing arm 6, make big swing arm 6 take place the swing, and then drive the motion of connecting rod 7, make connecting rod 7 drive weft swing arm 8 and remove towards the lead screw, and lead screw 17, adapter sleeve 19, servo motor 12, mounting bracket 16, mounting panel 18, the adjustment mechanism that fixed arm 15 and axle sleeve 14 constitute is a whole, so when the ascending thrust of slope of weft swing arm 8 is received to lead screw 17, adjustment mechanism wholly rotates, and the woof axle 10 that links to each other with axle sleeve 14 begins to rotate simultaneously under adjustment mechanism's drive, because driven swing arm fixes on woof axle 10, and then driven swing arm outwards rotates certain angle, and then stimulate shuttle box 4 outwards to remove, and then realize sending out of weft.
Because the weft on the drum 2 is in the full-line state, the resistance is small, the distance between the outmost weft and the weft shaft 10 is short, the weft delivery amount is large under the same displacement condition of the shuttle box 4, the weft on the drum 2 is gradually reduced along with the continuous delivery of the weft, and the weft on the drum 2 is in the shallow state, the resistance is large at the moment, the distance between the outmost weft and the weft shaft 10 is large, and the weft delivery amount can be reduced under the same displacement condition of the shuttle box 4.
By setting parameters of the servo motor 12, when the bobbin 2 is full, after the servo motor 12 rotates, the lead screw moves towards the connecting sleeve 19, the lead screw returns to the initial position, the distance between the lead screw and the weft swing arm 8 is the largest, the rotation angle of the weft shaft 10 is the smallest, the swing angle of the driven arm 13 is the smallest, and the distance for the shuttle box 4 to move outwards is the smallest; when the weft thread reduces gradually on drum 2, servo motor 12 rotates according to the parameter of setting for, make lead screw 17 outwards stretch out, and the distance between the weft swing arm 8 reduces, the stroke of weft swing arm 8 is unchangeable, shorten with the distance of lead screw spare, make the lead screw earlier contact with weft swing arm 8, and then the grow of 10 pivoted angles of latitude axle, make driven swing arm turned angle increase, and then make the distance of shuttle case 4 outside removal increase, can make the weft delivery volume of this moment and compare the delivery volume when filling up drum 2 equivalent, thereby make fishing net weave in-process mesh size keep unchangeable, avoid big or small mesh problem.
The present invention is not limited to the above embodiments, and based on the technical solutions of the present disclosure, those skilled in the art can make some substitutions and transformations to some technical features without creative labor according to the disclosed technical contents, and these substitutions and transformations are all within the protection scope of the present invention.
